Abstract (en)
The invention relates to a process for producing a polymer, comprising polymerization of at least of one alpha-olefin monomer in the presence of a prepolymerized catalyst obtainable by subjecting a catalyst to a prepolymerization with at least one alpha-olefin monomer such that the prepolymerized catalyst comprises 200-400g polyolefin/g catalyst and the polyolefin has a weight average molecular weight of at least 25,000 g/mol, to a process for producing a prepolymerized catalyst, to such catalyst and to its use.
